The AMC Barrel Allocator Demonstration

Avoiding Bumping Lower Priority Missions

We are still left with two unschedulable missions. This time
we just select both of them and ask the system to automatically bump lower
priority missions. Three missions are now marked as unassignable.

However,
we have already bumped those missions in the previous round and we do not want
to touch them anymore. We undo the last action by clicking on the undo arrow in
the mission window toolbar. In this case we need to click twice because we
have scheduled two missions.

Now we select the three lower prirority missions and use the
command Allocate | Lock
to instruct the system not to bump these missions.
When we select again the two unassignable missions and ask the
system to automatically bump lower priority missions, two other missions are
bumped and end up as unassignable.
